I Application filed June 29, 1911. Serial No. 6351997.

To all whom it may concern: 7

Be it know nthat' I, DAIEiY ELLEN SMOOT, a citizen of the United States, residing at Piedmont, in the county of Wayne and State of Missouri, have invented certain new and useful Improvements in Devices 'for Poisoning Rodents,fof which the following is aspecification.

This invention has for its object theprovision of novel means for exterminating rodentsv by poison.

In carrying out the invention it is contemplated to provide a flat body composed, primarily, of layers of cardboard, strawboard, or the like, between which is interposed a poisonous substance, said body being intended to be tacked or otherwise secured over'ajrathole or other passage used by rodents.

The intent of the inventio n is to make the of a material which may be readily gnawed through by rodents so-that the lat-v ter will be poisoned and killed; the article being soconstructed, that the poisonous substance incorporated in the body is not exposed so as to give rise to likelihood of accidental poisoning. of human beings or domestic animals through contact with the poisoning means descrbed.

The invention is designed furthermore, in its preferred form, to afford special advantages. from the standpoint of an article of manufacture, in that it may be constructed at a nominal cost,and a number of oisoningbodies or devices struck or cut rom' a single blank of material.

With the above and other objects in view, a complete understanding of the invention will be accomplished by reference tothe following description, and accompanying drawings, in which:

Figure 1 1s a sectional view showingt-he poisoning device secured over a partly closed opening such as are used by rodents. Fig. 2 is a plan view of the device alone. Fig. 3 is a viewshowing a blank of material such as may be employed'in making the poisoning devices. Fig. 4 is a view showing the invention in its commercialform.

In the. following description and in the accompanying drawings similar reference characters refer to similar parts.

Describing the invention specifically, the numeral 1 denotes a floor or other body in which is located an opening to form a rodent passage.

The layers 3 3 designates the poisoning device which consists of layers 3' and 3, preferably of cardboard or other material through which a rodent can readily gnaw an opening. and 3" of the device 3 are preferably formed with register perforations or apertures l, and between the said layers is interposed the poisonous substance 5 which may be a composition of Paris green er other poisonous ingredients, susceptible of use for the purpose of the in vention.- The poisonous substance 5 is'preferably applied to the lower layer 3" of the device- And if the layers are of separate pieces ofmaterial, the poisonous substance will, be spaced from the .edges of the layers as shown mostclearly in the drawings. Furthermore, the poisonous substance will be spaced from the periphery of the single opening in the device 3 formed by the apertures 4 of said layers. The poisonous substance 5 is therefore not exposed at any point of the device so that in the ordinary handling of the latterin commercial use there is no likelihood of harmful results; the poisoning function of the device can not be accomplished in ordinary usage of the same except when the material from which the layers 3 and 3 are made is gnawed through, such operation being readily per formed by the ordinary rodent, with disased on a medial longitudinal line to provide at one end aclosed edge, and to form the layers above mentioned, said layers are connected together by an ordinary adhesive shown at 6, or'any other means. The blank of material is folded on .the medial line shown at 7 in Fig. 3, and it assumes the'form shown in Fig. 4, and since the blank is perforated on the lines shown at 8, the several devices formed in the above {manner may be separated one from another. and sold singly.

Having thus far described the invention, what is claimed as new is: 1. As a new article of manufacture, a poisoning device composed of layers of ma terial connected at adjacent sides, the layers being formed with registering apertures providing an opening through'the device, and a poisonous substance interposed between said layers.

2, As a new article of manufacture, a poisoning device composed of superposed layers of material adhesively connected together, and a poisonous substance interposed between said layers, the poisonous substance as aforesaid being spaced from the edges of the layers and wholly inclosed by the latter, the layers being formed with registering apertures centrally thereto, forming an opening through the device, the poisonous substance being spaced from the edges of the apertures. v

3. As a new article of manufacture, a rodent poisoning device made from a single blank of material folded upon itself to form layers, said layers being provided with registering apertures therein forming an open
